Can't decide: Panasonic LUMIX 20mm f/1.7 OR the new Olympus 45mm f/1.8?

Its one half stop difference from 1.8 to 2.8.

So 1.4, 2.0, 2.8, 4.0, 5.6, 8. are full stops.

I have them both and I use them both - a lot. I would say for over all use, it would have to be the 20mm. Probably the most versatile lens for m4/3. But for portrait, then it's the 45. I also have the 14, but hardly ever use it.
